Are Krakatoa and Krakatau the same?
One of the most powerful volcanic eruptions in recorded history occurs on Krakatoa (also called Krakatau), a small, uninhabited volcanic island east of Sumatra and west of Java, on August 27, 1883.

Which volcano made the loudest sound in history?
Krakatoa
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
What is louder than Krakatoa?
In air, the sperm whale would still be extremely loud, but significantly less so — 174 decibels. That’s roughly equivalent to the decibel levels measured at the closest barometer, 100 miles away from the Krakatoa eruption, and is loud enough to rupture people’s ear drums.
When did Krakatoa explode?

What made Krakatoa so explosive?
Originally Verbeek thought that Krakatoa was so fierce because sea water flooded into the volcano, reacting with molten lava; the build-up of pressure from the resulting steam would have led to an enormous blast. The best way of predicting a blast is to record seismic activity within a volcano.
Where was the island of Krakatoa in 1883?
On the morning of Aug. 26, 1883, the residents of the island of Krakatoa in the Sunda Strait of Indonesia, then-Dutch East Indie, arose like it was any other day. They went about their business as smoke trailed from the three volcanic cones that dotted the island.
How many people died in the Krakatoa eruption?
At least 36,417 people died, and many more thousands were injured, mostly from the tsunamis that followed the explosion. The eruption destroyed two-thirds of the island of Krakatoa. Eruptions in the area since 1927 have built a new island at the same location, named Anak Krakatau (which is Indonesian for “Child of Krakatoa”).
Why was the eruption of Krakatoa so loud?
It is possible that Krakatoa created one of the loudest sounds ever generated on earth, rivaled only by the volcanic eruption of Mount Tambora in 1815. Pieces of pumice were light enough to float, and weeks after the eruption large pieces began drifting in with the tides along the coast of Madagascar, an island off the east coast of Africa.
How tall was the ash cloud at Krakatoa?
Reports started coming in from ships sailing through the busy waterway, including the German warship Elizabeth, whose captain reported seeing a cloud of ash above Krakatoa stretching some 6 miles high. Things had quieted down by the end of the month, though smoke and ash continued to emerge from Perboewatan crater.
